Application filed J une 9,1908. Serial No. 437,528.

'ford and State of Connecticut, have invented a new and improved Cleaning Apparatus, of which the following is aspeciica- My invention relates to the class of devices specified, and an object of the invention, among others, is to providea device of this class having numerous novel features of advantage and utility.

pattern, preferably A form ofdevice in the constructionand use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawings, in.which The figure is a view .in elevation of a device embodying my invention with parts broken away to show construction.

' My apparatus contemplates the dow of a current of air that by shall remove dirt, and other impurities which are carried along with the current, the device contemplating a suitable apparatus for creating flow of a current of air sufficientv for the required purpose. f lnthe operation of such devices it is desirable in many cases-to use water asa means for loosening dirt, this being in the nature of -ascrubbingprocess, the tools embodying brushes and like devices for facilitating the scrubbing. and-Water are carried vthrough the tools and alongftlie tubing. in order to separate the water, dirt and other impurities from theI air, or at least a considerable'portion thereof, before the' latter reaches the device 'fon creating the dow, li have so arranged my apparatus that it is especially applicable in effecting the separation in which` water is a considerable factor.

ln ythe accompanying drawings the numeral denotes a device for creating a iow of air and this may be of any approved one that is known as a turbine exhauster. rlhis exhauster'is provided with receptacles 6 which may accumu- -late 'any of the minor parts of the impuri- 7 having an outlet- 8 which. may lead to any suitable source of exhaustv ties, and a stack for the air.

A tubular support 9 rises from the shellof the exhauster (the device for creating a How of air), this support being Connected with the force of such flow rihe air and commingled dirtl thereof into the annular space ae' ima Side of 'en device. Upon ne@` tubea separator 10 is mounted, that, in its preferred form, consists of a case 11 having an inlet 12 and an impurities outlet 13. rlhe inlet 12 is preferably tangentially arranged with. respect tothe case: and has a tube 14C of proper lengthgand size to conduct the currentof dirt-laden air, this-tube' terminating in a tool 15 by means of which the dirt and air vare removed.

Within the separating chamber in the case 11 a screen 16 is arranged, 'preferably tapered or offrustof'conicalform with the smaller end downward and communicating with thetubular support 9.

A flange 2O is located within the case 11 at the bottom providing an annular space 21. rlhe size as. to diameter of this flange may vary within the limits of the dimensions of the chamber within the case, and ll con sider a satisfactory construction to reside in making this iange of a size approximately that of the tubular support 9, and'if desired, this support may be projected within the case to a sufcient exten-t to provide this dange. The lower end of the screen 16 rests upon the flange 20.

T An inletpipe 22 may be extended into the case 11 and provided with a valve or other suitable means 23 for controlling flow of water, this for the purpose of flushing the case when desired.

rlhe flange may be of any' desired height or length to suit any special requirement,'in some instances it may be found of advantage to have a construction in which the screen 16 is absent, the flange 20 extending suiiiciently within the case to serve allpurposes.

fn the operation of the device the clean y ing tool being "applied to a surface, as a floor-having water thereon and the device for creating a flow of air being in operation, the commingled dirt, water and air are drawn into the case 11 through the pipe 14: and inlet '12. The centrifugal motion imparted to this current by the action of the device 5 causes the heavier parts of the material, and especially the water, to be thrown outward a ainst the walls of the case from which it ows downward to the bottoml 21 and from 4thence through the outlet 13. Any coarser particles of the material arev intercepted by the screen 16, and passing along the 'same and through the tube 9 are deposited in one V'2'0 ,Y 'Inithetrap herein' shown for accomplishof the receptacles 6.-l This prevents any danger gof obstruction inthe voutlet from the C t n r i l It'will be understood that it is essential to maintaina water seal -within, the trapin l order to preventfthe flow of impurities and obnoxious gases pastsaid trap into. the apparatus, andi thence into 'the room' in which.

the apparatus may be located.' In "a-'trapof common'and ordinary construction the suction ofthe apparatus would be such asv to draw the ."limitedamou'nt of water from the v trap into the apparatus,and to prevent this applicant .constructs his trap to. contain, whenthe apparatus is' not in use,suiiic1ent water'to:` resist vthe suction' of the. apparatus,

the traporfconnectionsj. also being oonstructed to* containthis t amount of y`fwacer wlien-fth l apparatus Vis in operationand` without backflow into .such apparatus.

ing this purpose the shorter arm 19 is of such 'length that.'sufficientV water willbe containedlinbolth arms of the trap, before outflow fromthe outletI from Athe arm 19, 4to resist the'sucti'on'of the apparatus, and the longer arm `18. of the trap is of a length to `contain enough water to resist the suction of'the apparatus and prevent back-flow of the water into such apparatus. I

When'the apparatus isv started water will bev drawn upwardin the long arm to a certain extent, and'will, ofcourse, be lowered inthe shorter arm 19 -to same extent. The

waternowcolle'cted inthe cleaning tool iowing outthrough theoutlet 13 and'pipe 17 will further raise the water an equal distween said 'ange andthe wall of the receptacle, an outlet from Said receptacle, said outlet being connected. with the device for creating a lowof fluid, -a screen of conical shape open vat its upper end located within saidy receptacle and with its smaller end opening into said outlet within said flange, Aand means for delivering matter to be sepal rated into said receptacle.
